S IT ERLAND, ASSIGNOR, BY MESNE As SIGNMENTS, TO THE FIB M SCHWAIBFBI-IRES 85 00., SOCIETE 'ANONYIVIE, OF LA CHAUX-DE-FONDS, SWITZERLAND,A CORPORATION OF SWITZERLAND WATCI-IGASE Application filed March 21,1929, serial n5.

' watchcase which normally entirely covers the dial plate of the watchinserted therein. Another object is to provide meanson the'case foreasily and'readily uncovering the dial platein order to see the time.

A practical embodiment of my invention is illustrated in theaccompanying drawing wherein:

Fig. 1 is a plan view of the watchcase. Fig. 2 is a section throughII-II of Fig.1. Fig. 3 is a Visit" of the casing from. underneath, thebottom cover having been removed.

The watchcase as representedcomprises a case body forming the bottompart'l and a bezel 2 having a rectangular opening 3 pro vided thereinwhich is adapted to receive crystal in the grooved edge ,11 thereof. Tothe bezel 2 are hinged in l two lids 5 and (3. Each lid has a backwardlyextending projection 7 which is subjected to the action of spring 8.This spring maintains the lids in closed position, in which positionthey cover the dial plate of the watch. .9 are push levers pivoted onthe bezel in 10 and penetrating through the walls thereof to the outsideof the case. When these levers are pushed to{ wards the interior of thewatchcase they act on the projections? against the sprin 8 and turn thelids 5 and 6 into open position.

It will be understood that the invention is not limited to the detailsof construction as represented in the drawing. Particularly the devicefor operating the lids could be difierent. For example there could beprovided for each lid a rack sliding in the casing and meshing with apinion disposed on the axis of rotation of the lids.

I am aware that heretofore it has been proposed to provide a watch casewith two hinged lids each provided with a spring tending to close it,which said springs can be simultaneously flexed by a slngle plungermounted in the watch case wall. In the construction herein shown anddescribed, however, by the use of separate, oppositely disposed movablemembers each cooperating with a separate lid, a resistance equivalent to348,954, and. in Switzerland. A ril 12, 1928.

that of only one spring has'to'be overcome by the operator inorder toopen the two lids, each spring serving as the means of transmittingsaidpressure to the other. This constitutes animprovement over the abovementioned prior construction in which the sum of the resistances of thetwo springs must be overcome before the two lids can be opened.Obviously, therefore, the same rapidity and positiveness of closure oflids can'be attained with my inventionupon application by the user ofonly half the force required to secure the sameresult in the case ofthe-prior construction.

I claim: Y

1. A normally closed pocket casing, adapted to contain an article to bealternately disclosed and concealed, comprising, in, combination,asubstantially flat, hollow bodyhaving an opening of relativelyconsiderable area in one face and two oppositely disposed openings inthe walls thereof, relatively near the outer edges of the cover platestwocooperating cover plates for said opening hinged adjacentv oppositeedges thereof, a member located and operatively mounted in each of saidsmaller openings and-operatively connected to oneor the otherof saidcover plates, and spring mechanism normally holding said cover plates inclosed position; whereby, when said casing is held between the thumb andfingers of one hand inward pressure thereby exerted on said movablemembers will open the case. 7 V

2. A combination such as defined in claim 1 in which said doors arehinged to said casing with the axes of said hinges parallel one toanother and extending at right angles to the common line of slidingmotion of said mova ble members.

7 3. A combination suchas described in claim 1 in which sald motiontransmlttmg mechanism consists of a lugextending fromeach door near thehinge thereof, and into the casing interior in the pathof one of saidmovable members. I

In testimony whereof I affix my signature. SAMUEL GLAUSER PERBIN.
